Specification of Letters Patent.

Patented April 30, 1907.

Application filed April 2, 1906- Serial No. 309,420.

To ctZZ whom it may concern.-

Be it known that I, AARON F R-ANKENHEIM, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Means for Connecting Cable-Chains; and I do hereby declare the following to be a full, clear, and exact description of the .invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in means for connecting cable chains and particularly to the peculiar structure of a chain shoe employed in the construction of any object in their attachment to cable chains of conveyers.

The object of the invention is the provision of means for facilitating the attachment of any object to endless traveling supporting chains.

In the drawings :Figure 1 is a view in vertical section of a cable chain link showing my chain shoe secured thereto in a horizontal position. Fig. 2 is a View in side elevation of the chain shoe as applied to a horizontal link of the chain. Fig. 3 is a fragmentary view of an object for attachment to the chains and embodying means for attaching the improved shoe in a horizontal position. Fig. 4 is a top plan view of the shoe as applied to the vertical chain link. Fig. 5 is a view in side elevation of one of the sections of the shoe as shown in Fig. 4. Fig. 6 is an end view, in elevation, of the shoe as shown in Fig. l. Fig. 7 is a central, transverse, sectional view of the said shoe, showing the means of attachment to a horizontally positioned object. Fig. 8 is a View in side elevation of one of the sections of the shoe as applied to a horizontal chain link, shown in Fig. 2. Fig. 9 is a vertical sectional view of one of the sections of the shoes as applied to the horizontal link, taken on line 9-9 of Fig. 8. Fig. 10 is a View of an object showing the means for attaching the shoe vertically. Fig. 11 is a transverse, vertical, sectional view of the shoe, showing the same connecting an object to the horizontal link of the chain. Fig. 12 is a view in end elevation of the member shown at Fig. 6, seen from the opposite end.

Referring to the drawings by numerals, 1 designates an object to be attached to a against a vertical link 3.

chain and here shown as a conveyor bar. The chains used with this device are formed 5 5 of vertical links 3 and horizontal links 4. Each object is attached at one end to a vertical link of one of the chains, Fig. 1, and at its opposite end to a horizontal link of the other chain, Fig. 2.

Referring particularly to Fig. 3, the object 1 .is provided at one end with a recessed portion 5 upon each side of the web 2. A transverse tapered aperture 6 is formed in the web. The shoe 7 comprises sect ons 8 and 9. Refer-ring particularly to Fig. 7, the section 8 of the shoe is provided with a hollow lug or boss 10 formed upon its inner surface. The section 9 is provided with an integral pin or lug 11, which is adapted to be positioned within the horizontal boss or sleeve 10 of sec tion 8. The upper portion of each of the sections of the shoe 7 is flared outwardly, as at 12 for the purpose of fitting snugly against the curved portion of the web. Furthermore, each section is provided with a rib 13 defining depressions 13 for the accommodation of the adjacent horizontal link, and by which the sections are held in engagement with the web and the object properly posi- 8o tioned and maintained upon the chain. Each section is provided with a hook 14 and with an outwardly flaring front end 15. The flared ends 15 of the shoe 7 are adapted to lit The shoe is first attached to the web of the object and then the shoe is hooked into a vertical link and subsequently, the object is attached at its opposite end to a horizontal link. The hollow boss or sleeve 10 is posio tioned within the aperture 6, and the pin 11 is positioned within the boss for securing the sections of the shoe to the web of the object. After the hooks 14 have been positioned within the vertical link of the chain, the shoe 5 will be fixedly retained upon the web for the reason that the boss 10 and pin 11 form a rigid fastening means for preventing any longitudinal movement and thereby displacement upon the web, and as the front portions of the sections are outwardly flared, as at 15, they will assist in forming a permanent lock for the shoe after it has been hooked in place upon the vertical link.

The opposite end of the web 2 from that in 10 5 which the aperture 6 is formed, is provided with a transverse aperture 14:, within an inverted U-shaped depression 15. The sections of the shoe 16 are of similar structure, and it will, therefore, only be necessary to specifically describe one of the same. The sections of the shoe are first positioned within a horizontal link of the chain before the web 2 is positioned between the same, Fig.

11. Each section of the shoe comprises a body 17, provided at its lower end with a hook 18, and at its upper end with a rib 19, defining a depression 19, adapted to engage a portion of the vertical link, Fig. 11. The upper end of each of the sections is also provided with a curved flange 20 bearing against the body of the object and the upper wall of the depression 15. It will be understood that the shoe, as applied to the vertical link of the chain is practically and materially the same structure as to the chain'links, as the shoe structure is, as applied to the horizontal link, excepting that as applied to the vertical link it permits the links to pass about a chain wheel, or sprocket wheel, for which it is so adapted, and which is not necessary in the shoe as applied to a horizontal link of the chain. The exterior extension of the shoes embodying their connections to and upon either end of the object, are merely adapted to the functions to which they are to perform in facilitating the application and lockingof the object to two conveying chains. After the shoe has been secured to one of the vertical links of one of the endless chains and the sections of the shoe have been positioned with in a horizontal link of the other chain, the web is dropped down and positionedbetween the sections of the shoe within the substantially V-shaped socket or recess formed by the longitudinally curved, inner wall of each section, Fig. 11. Subsequent to the positioning of the web 2 between the sections of the shoe, suitable fastening means 21, as for instance, a rivet, or spring cotter, is positioned within the apertures 22 of the sections of the shoe and the aperture 14. formed in the web, the apertures 22 and 14 registering when the parts are in their assembled position, Fig. 11. It will, therefore, be obvious that both the shoes as applied horizontally or vertically fit snugly against the object and the links of the chains thus forming an admirable securing means for fastening the bars of a conveyer mechanism to the endless carrying chains thereof. The hooks 18 of the sections of the shoe as applied vertically extend in opposite directions, for the reason that as they are similarly constructed, or of one pattern when positioned upon opposite sides of the web 2 they will, of course, cause the hooks to extend in the direction stated.

In the embodiment of the shoe, illustrated in Figs. 4 and 5, I have shown a straight, rear edge 23 formed upon each of the sections of the shoe. It will be obvious that certain alterations and modifications may be made without departing from the spirit of the present invention, as the rear edge 23 may be of an angular or curved formation which also applies to the inner surfaces between the sections of the shoe as applied to either link of the chain, in the embodiment of the object connecting said chains.
